粮油作物 水稻 大力推广早稻耐寒旱育秧技术和早稻抛秧育秧技术。早育秧于3月中旬播种,播前苗床精细整土、轻压调平,以便谷芽落土深浅均匀,每667平方米秧床播常规稻50公斤或杂交稻15公斤—20公斤,播后用火土灰拌细土盖谷1厘米厚,再每平方米苗床用敌克松1克加呋喃丹4克对水1公斤喷施,然后盖膜。早稻通气湿润秧田育洗插秧,应于春分至清明按品种生育期迟早先后播种。山区杂交中稻生产地区蓄留再生稻,应于3月中旬播种育旱秧。 旱粮 ①春玉米地膜育苗移栽期:3月中旬,高寒山区相对迟7天左右;春玉米直播比育苗移栽播期迟15天左右。 Grain and Oil Crop Rice Promote Early Cold Hardiness and Nursing Seedling Raising and Early Rice Seedling Raising Seedling Technology. Early seedlings planted in mid-March, before sowing seedbed fine soil, light pressure leveling, so that the average depth of Valley fall, every 667 square meters seedling bed conventional rice 50 kg or hybrid rice 15 kg -20 kg, after sowing Mix the soil with the soil and mix the soil with the soil 1 cm thick, and then per square meter of seedbed with the enemy fleece fleece fleece fleece fleece fleece 4 grams 1 kg spray, and then cover the membrane. Early rice ventilation wet seedling planting seedlings, should be in the spring to the Ching Ming crop varieties will have sowing sooner or later. Mountain hybrid rice storage areas in the ratooning rice, should be planted in mid-March drought seedlings. Dry grain ① spring maize plastic film seedling transplanting period: in mid-March, relatively cold alpine mountain 7 days later; live corn than sowing transplanting sowing later than 15 days.
